But 12 is just 1, so:x2 + y2 = 1 equation of the unit circleAlso, since x=cos and y=sin, we get:(cos(θ))2 + (sin(θ))2 = 1 a useful "identity"Important Angles: 30°, 45° and 60°You should try to remember sin, cos and tan for the angles 30°, 45° and 60°....
tan(α)=sin(α)cos(α)=yxtan(α)=cos(α)sin(α)=xy Which, of course, will give us the same result. Another method is using our unit circle calculator, of course. 😁 But what if you're not satisfied with just this value, and you'd like to actually to see that ta...
Calculate the coordinates for a point on the unit circle given the central angle in radians or degrees. You’ll also get the sine, cosine, and tangent in the results. Angle (θ): Solution: x = cos(θ) y = sin(θ) tan(θ) Learn how we calculated this below scroll down ...
